ABSTRACT
This chapter focuses on evaluation as operated in relation to the Israel High School Biology Project (IHBP). In 1964, a group of selected Israeli high school biology teachers, under the direction of Professor A. Poljakoff-Mayber undertook the task of producing a new high school curriculum in biology. Unlike curriculum projects which have conceived their primary function to be the design and development of curriculum materials, the Israeli Biology Project has placed at least equal emphasis on providing the necessary conditions for adequate implementation and for assessment and evaluation. Although this evaluation yielded data on limited aspects, it was sufficient to show that the Biological Science Curriculum Study programme could be used successfully in many American classrooms. The IHBP evaluation results have been communicated to a variety of audiences. Assessment and evaluation are extremely powerful means of affecting what is taught in schools and how it is taught.
